7- Claims.

'I'his invention relates to vacuum cleaners.

The general object is to provide a vacuum cleaner-which is compact, easily manufactured and which is highly efficient in use.

One of the specific objects of the invention is to provide a vacuum cleaner including a novel arrangement of a dust sack.

Another object is to provide a novel means for holding the dust sack of a vacuum cleaner in position.

A further object is to provide a novel manner of'supporting the hose and cord of a vacuum cleaner.

Other objects and the advantages of my invention will be apparent from the following description taken in connection with the accompanying drawings wherein: v

Fig. 1 is a central sectional view of a vacuum cleaner embodying the features of my invention;

Fig. 2 is a rear elevation of the cleaner;

Fig. 3 is a fragmentary sectional detail showing the inside of the dust sack well;

Fig. 4 is a sectional detail of the de-mothing receptacle;

Fig. 5 is a front elevation of my improved nozzle;

Fig. 6 is a section taken on line 6-5 of Fig. 5;

Fig. 7 a section through my novel brush; and,

Fig. 8 is a top plan view showing the 'manner in which the hose is supported.

I have shown my invention as embodied in a vacuum cleaner indicated generally at in. As shown the cleaner includes a body l l which comprises a receptacle H2 at one end and has a motor housing 63 at the other end. The receptacle l2 is preferably made of sheet metal bent to form a plane wall portion l2 and an arcuate wall portion H2". The receptacle l2 has an angular ring Ml secured in the upper end thereof by bolts 95. The ring is rabbeted as at it to receive a flange ii to which a fabric dirt bag B is secured.

The ring it is provided with a closure portion 66 from which an ofiset conduit 19 extends. This conduit is provided with a cylindrical end portion 20 in which the skirt 2! of a cap 22 is fitted. The cap 22 has a tubular member 23 mounted to swivel thereon and a hose 24 is connected to the tubular member 23.

In the receptacle wall portion I2 I provide a. foraminous partition 25 over which a guard member 26 made of cloth is arranged. This guard member 26 has a peripheral metallic rim 2! which is held by a suitable clamping member 28 in such a manner that it can be readily removed when desired.

A guard member 29 made of wire bent to substantially inverted U-shape is secured at the bottom of the receptacle l2 and projects upwardly in front of the guard member 26, to prevent the bag B from being drawn against the guard member.

A motor 30' is suitably mounted in the motor housing l3 and is connected by leads 3| with the switch 32 from which a power cable 33 extends. The motor housing I3 is preferably cylindrical in cross-section and is provided at its front end with a collar 34 which is rabbeted as at 35.

On this rabbeted portion a filtering disk 35 is supported and is engaged by a flange 3? on a closure member 38 Which closure member includes a discharge orifice 39. I

The armature shaft of motor 30 is provided with a fan 40 which may be of suitable configuration. The forward end of the body is provided with a pair of skid members 4! which are arranged under the dust bag receptacle l2 and with a pair of rollers 52 which are arranged under the heavier motor end on the housing l3. The

rollers 42 are held in place by bearing supporting a members 42* which also serve as guards to protect the wheels against striking furniture. The construction is such that by pulling on the hose 24 which is attached to the lighter forward end of the sweeper this end will be lifted slightly so that the entire structure can be readily moved about. A rubber bumper 42* extends around the receptacle 82. The forward end of the body has a handle bracket 33. secured thereto. This handle bracket engages one end of a handle a l and is secured thereto by a screw 45. The other end of the handle member engages the upper end of the receptacle wall portion l2 and is secured thereto by a screw 46.

The closure portion l8, the cap 22, the closure member 38 and the fitting which is inserted in the orifice 39 are each held in place by a quick detachable coupling which includes a fixed member 41 under which a portion of the flange of the closure is inserted and a pair of clamping members 48. Each clamping member includes a central pivot 49 and a rotatable finger portion 50, the under surface of which is inclined as is A demothing receptacle 53 is shown in Fig. 4.

This demothing receptacle comprises a pair of complementary cuplike members 54 and 55 which have flanges 56 projecting therefrom. These flanges 56 are adapted to fit the rabbet 35 when the disk 36 is removed and to be engaged by the flange 31 on the closure member 38. The demothing receptacle 53 may receive a suitable material and when the air is blown over this material a portion of the demothing substance will pass into the air stream.

The dirt bag B may be provided with an annular ring-like member 58, which serves to hold the bag in its normal operating position and which facilitates insertion and removal of the bag.

This ring 58 is of smaller diameter than the mouth of the receptacle l2 and the bag preferably tapers to facilitate inserting and removing the bag and also enables the bag to be readily turned inside out when discharging its contents.

In Figs. 5 and 6 I show a nozzle 59 secured to the hose 24 by a swivel member 60 which has a flange 6| engaged by a collar 62 mounted on the nozzle. The collar 62 has a planar body portion 63 from which a foot 64 projects. This foot is provided with downwardly extending teeth 65. A suitable rubber bumper 66 extends around the nozzle.

In Fig. 7 a brush is shown which includes a body 68 which has a central passageway 69. The body is provided with bristles arranged about the passageway 69 and is provided with an orifice portion H which is suitably connected to a swivel member I2 for attachment to a hose.

In operation the motor is started and the nozzle is moved over the surface to be cleaned. In case any threads or other fine materials adhere to the surface being cleaned the nozzle is moved downwardly until the teeth 65 engage the thread after which the nozzle is given a slight movement thus loosening the thread after which the nozzle is moved to normal position and the thread is drawn into the nozzle.

If the demothing operation is required the closure 2! is inserted in the orifice 39 after the demothing material container 55 which has been inserted in place as shown in Fig. 4.

To empty the dust bag the closure is removed and the dust bag turned upside down. Due to its tapered construction and the weighted mem-- ber in the dust bag the latter will turn inside out thus enabling it to be easily emptied without greatly disturbing the contents. When the op-' erator is through cleaning the hose is arranged so that a portion of the hose engages the clip 52' and the other portion is twistedaround the receptacle and housing of the cleaner. The power cord is also wrapped about the body so that the entire cleaner can be very readily picked up and carried with one hand.

From the foregoing description it will be apparent that I have invented a novel vacuum cleaner which is highly eflicient in use and which can be economically manufactured.
